The Lowdown
Alright, grab your board, it’s Rusty here. Let’s look at what we’ve got coming up for Jaconé over this 16-day window. It’s a bit of a mixed bag, but there are certainly some gems if you’re patient.
The first few days are pretty average, with small, short-period swell. We’re looking at clean conditions but not much power. Thursday the 6th has some rideable 5ft waves from the ENE with a 7-second period, but the energy is weak, only 401. It’s surfable but nothing to get too excited about. Friday is smaller, and Saturday the 8th is a write-off for surfing. The swell is weak and short-period, but the wind is up and messy, making it poor. Expect a few days of small, ordinary conditions through the weekend.
Now, here’s when it starts to get interesting. Sunday the 9th morning, the ocean comes alive. We’ve got a solid 7ft of SSW groundswell with a 14-second period, and the energy jumps right up to 1671. The wind is glassy, absolutely dead. This is a standout morning for experienced surfers. This is the kind of swell that has real push and shape to it. However, that same afternoon the wind swings onshore and gets fresh, turning it lumpy. You’ll want to get out early to catch the good part.
The swell from Sunday hangs around through the middle of the week but the wind is onshore and choppy, so it’s messy. Monday and Tuesday will be big but messy, with cross-onshore winds and rain on Tuesday. Not the best windows. By Wednesday the 12th morning, the wind backs off to a light cross-offshore, cleaning up that 7ft of S swell. That’s another solid call for experienced surfers, with energy at 1350. It’s still got some size but is much cleaner.
Thursday the 13th morning sees a gentle offshore wind and 6ft of S swell, making for very good conditions. This looks like a great, clean day. Then after a few average afternoon sessions, Friday the 14th morning is a proper glass-off. The wind is dead calm and this long-period S swell, a 16-second monster, is pushing in at 4ft with energy of 1181. It’s a beautiful, clean morning of powerful, peeling waves. A real standout.
The weekend of the 15th and 16th gets messy again with onshore winds. There’s plenty of size, over 7ft, but the quality drops off, and Saturday afternoon is just onshore mush. The 16th is cleaner with a cross-offshore wind, but the swell is shorter period and a bit jumbled.
Looking into the second week, things are promising but less certain. Monday the 17th afternoon, there’s a big push of SE swell, up to 10ft, with strong offshore winds. The energy is huge at 2233, but that’s getting serious. This is only for experts, and it might be too big for this break. It will be powerful and heavy, a real handful.
After that, we settle back down to more moderate, fun-size waves. Tuesday the 18th has clean 6ft E swell with offshore winds – a nice, clean day. Then we get a bit of a lull mid-week with smaller surf. The period drops off and the energy weakens.
The forecast for Thursday the 20th and Friday the 21st shows the next solid pulse. Friday the 21st morning looks fantastic on paper: a 7ft SSW groundswell with a 13-second period, clean offshore winds, and energy of 1496. It’s another classic Jaconé morning. So, those are the real standouts: Sunday morning the 9th, Friday morning the 14th, and the long-range call for Friday the 21st. Get on them if you can.
Remember, there will be some bigger, messier days too. When it’s over 8ft and the wind is onshore, it’s probably more interesting for the kite surfers than us paddle surfers. Stay safe.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
